1 0 all whom it may concern Be it known that I, Lno SoLHnm, a citizen ofthe German Republic, and residing at Dusseldorf, in the German Republic,have invented certain new and useful limprovements in FlushingApparatus, of which the following is a specification.

The present invention has reference to improvements in flushingapparatus such as used for instancein connection with water closets andurinals, and it relates more particularly to that class of: flushingapparatus in which, by the lifting of a siphon bell, variable quantitiesof flushing water may be discharged from the supply tank, for enablingthe user to obtain full or partial fiushings at will.

For the purpose of explaining the inven tion a constructional embodimentthereof has been shown in the accompanying draw-- ing, in which the samereference characters have been used in all the views to indicatecorrespondii'ig parts. In said drawing.

1, is a longitudinal section of the apparatus,

Fig. 2, is a plan of the same,

Fig.3, is a cross-section of the same, and

Figs. 4: and are a vertical section and a plan view showing the aeratingvalve of the siphon bell on an enlarged scale.

Fig. 6 is a fragmentary vertical section through the siphon means in theposition of rest, and Fig. 7 shows a similar section with the bell inraised position discharging water through the lower ports.

In the drawings the new flushing apparatus is shown by way of example inconnection with a water-closet, which latter comprises the severalelements well known in the art. The flushing pipe (I leads from thesupply tank a: to the closet bowl. From the siphon bell it depends thestandpipe a, rigid and concentric therewith, with its packing washer t,which pipe is provided near the upper extremity with passages q andbelow with passages The bell is operated by a rock-lever e, fulcrumed tothe tank at 2', to the other end of which lever is linked the pull rod 8with handle 9. The supply of water to the tank :is controlled by thevalve is operated by the float Z.

The operation of these parts is succinctly the following: If the bell uis lifted (Fig. 7) by a straight pull on the rod .9, water will flowfrom the tank through the passages 2 into the flushing pipe a. The

flowing water entrains air out of the pipe 12 and thereby immediatelycauses air rarefaction in this pipe. It now, after a short lift, thebell is let down again by letting go of the pull rod, this rare-factionwill suck up water standing under the bell, so that it will flow throughthe ports q into the central standpipe 12; and this will continue aslong as there is water in the tank, since the column of waterdischarging through the flushing pipe a con inuously siphons water outof the tank.

To the top of the hell it an air-vent pipe r is secured which isprovided with one or more'air inlets 0 adapted to be closed by a rotaryvalve 0 in the form of acylindrical cap having ports 0 corresponding tothe inlets 0. The valve 0 is adapted to be operated by means of an armit made integral therewith. The said arm is connected by a link f with ahorizontal arm Z; forming the upper end of the drawbar s and acting as alever. The drawbar is mounted along the wall, so as to be capable oflongitudinal and rotary motion. The rotary motion of the valve 0 islimited in one direction by a. cranked portion 41 of the link f and inthe other direction by the contact of the arm Z) of the drawbar s withan abutment piece to of the flushing tank x. The lower end of thedrawbar has a horizontal arm 9 which may be provided with instructionsfor the use of the apparatus.

It the rotary valve 0, the lever mechanism j, Z) and the handle 9 occupythe position shown in Fig. 2 by full lines, the air inlet of the tube 7'is open, because the lateral perforations of the tube 1" and cap 0correspond.

If it is desired to produce one or several weak flushing actions, it issufficient to turn the lever h from the position shown in Fig. 2 bybroken lines into the position shown by full lines, thereby opening theair inlets of the aerating tube, then to pull the drawbar s downwardand, when the desired quantity of water has been dis charged from theflushing tank, to release the handle and drawbar. This operation may berepeated several times, as long as the tank contains flushing water.

If it is desired to produce a strong flushing effect and to dischargethe whole contents of the flushing tank, the drawbar s, after the leverit has been turned into the position shown in Fig. 2 by broken lines andthereby the air inlet closed, is drawn downward and then released again(as is done in ordinary flushing apparatus).

With this invention it is possible, in case a full flushing action hasbeen started by mistake, to interrupt the same, for which purpose thehandle 9 is turned and thereby the air inlet opened.

On the other hand it is possible, to convert an accidentally startedpartial flushing action into a full flushing action by closing the airinlet, while the partial flushing is in progress.

While in describing the invention reference has been, made to asparticular example embodying the same I wish it to be understood that myinvention is not limited to the construction shown in thedrawing, andthat various changes may be made in the general arrangement oi theapparatus and the con struction of its parts without departing from theinvention.

1 claim:

1. In a flushing apparatus of the character set forth, in combinationwith a siphon bell including a central standpipe presenting top andbottom ports, and means for operating said siphon bell, an aeratingdevice for atwill preventing air rarei action within said siphon bell,and said aerating device adapted to be operated by a movement of saidsiphon bell operating means difi'erent from that for operating saidsiphon bell.

2. In a flushing apparatus of the character set forth, in combinationwith a tank, a fioatcontrolled water valve, and a siphon bell, includinga ported standpipe controlling the tank discharge, aerating meanslocated wholly above the normal water level in said tank andcommunicating with the interior of said siphon bell, means including apull rod for operating said siphon bell by a 1011- gitudinal pull andfor operating said aerating means by a rotary movement of said pull rod.

3. In a flushing apparatus of the character set forth, in combinationwith a siphon bell including a rigidly centrally depending portedstandpipe, pull rod means for operating said siphon bell for fullfiushings, and means for operating said siphon bell for partialflushings, comprising a ported casing on said siphon bell above thenormal water level and communicating with the interior of said bell, aported cap over said ported casing, and means operated by said pull rodmeans for relatively displacing said cap and said casing for placing therespective ports thereof into or out of register. i

l. In a flushing apparatus of the character set forth, the combinationwith a tank in cluding a float-controlled water inlet, of a siphon bell,including a ported standpipe, controlling the water outlet, siphonbrealn ing means comprising a casing having ports and communicating withthe interior of said siphon bell, a cap snugly holding said casing andpresenting ports adapted to be placed into or out of register with saidcasing ports, and said ports lying above the highest water level in saidtank, and means for operating said siphon bell for full flushings by astraight downwardly directed movement and for operating it for partialflushing-s by a combined downward. and rotary movement of one of theelements of said operating means, thelatter comprising a pull rod, acranked handle at the lower end thereof and a lever arm at its upperend, a rock-lever pivoted to said tank and linking said pull rod to saidsiphon bell, a lever arm extending laterally from said siphon breakercap, a link connecting said cap lever arm to said pull rod lever arm,and means limiting the operative displacement of said siphon breakeroperating means.

In testimony whereof I aflix my si nature.
